摘要： An additive manufacturing system including a base assembly and a tray assembly. The base assembly includes a build window, substantially transparent to electromagnetic radiation; a projection system configured to project electromagnetic radiation toward an upper surface of the build window; and a tray seat arranged around a perimeter of the build window. The tray assembly is configured to engage with the base assembly in an engaged configuration and includes: a tray structure defining a registration feature configured to engage the tray seat to locate an aperture proximal to the upper surface of the build window in the engaged configuration; and a separation membrane that is configured to laminate across the upper surface of the build window in response to an evacuation of gas from an interstitial region and configured to separate from the build window in response to injection of gas into the interstitial region.

摘要： A process for additive manufacturing of a resorbable implant to be implanted into a patient includes providing a biocompatible resin including a liquid light-polymerizable material that is resorbable after polymerization and an initiator. The process further includes actuating an additive manufacturing apparatus to expose an amount of the biocompatible resin to light to at least partially cure the exposed amount of biocompatible resin to form a layer of the resorbable implant and actuating the additive manufacturing apparatus to expose at least some additional amount of biocompatible resin to light to at least partially cure the exposed additional amount of biocompatible resin to form an additional layer of the resorbable implant and to at least partially overcure previously cured layers to cause at least some interlayer binding between the previously cured layers and the additional layer.

摘要： Matrix-filled liquid radiation curable resin compositions for additive fabrication are described and claimed. Such resins include a cationically polymerizable component that is an aliphatic epoxide, a multifunctional (meth)acrylate component, a cationic photoinitiator, a free-radical photoinitiator, and a matrix of inorganic fillers, wherein the matrix further constitutes prescribed ratios of at least one microparticle constituent and at least one nanoparticle constituent. Also described and claimed is a process for using the matrix-filled liquid radiation curable resins for additive fabrication to create three dimensional parts, and the three-dimensional parts made from the liquid radiation curable resins for additive fabrication.

摘要： A method of forming a dual cure three-dimensional object by additive manufacturing may be carried out by mixing a first precursor liquid and a second precursor liquid to produce a polymerizable liquid comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component (e.g., a second reactive component) that is different from the first component (e.g., that does not contain a cationic photoinitiator, or is further solidified by a different physical mechanism, or further reacted, polymerized or chain extended by a different chemical reaction). In the foregoing: (i′) at least one reactant of the second solidifiable component is contained in the first precursor liquid, and (ii′) at least one reactant or catalyst of the second solidifiable component is contained in the second precursor liquid. Once mixed, the three-dimensional object may be formed from the resin by a dual cure additive manufacturing process.

摘要： A three-dimensional printing system for solidifying a photocurable resin in a layer-by-layer manner at a build plane includes a scan module, a transparent plate, a sensor, and a controller. The scan module is configured to scan the light beam along two axes to address the build plane. The transparent plate is positioned in the optical path between the scan module and the build plane. The transparent plate has at least one reflective feature in the optical path. The sensor is mounted above the glass plate and is positioned to receive light reflected from the reflective feature. The controller is configured to operate the scan module to scan the light beam across the build plane, receive a signal from the sensor when the light beam impinges upon the reflective feature, and analyze the signal to verify a proper alignment of the light beam to the build plane.

摘要： A method for preparing a sacrificial support material for use in printing a three-dimensional (3D) article includes providing a water-soluble thermoplastic polymer composite including a water-soluble thermoplastic polyethylene oxide graft polymer having a polyethylene oxide polymer backbone, and from about 0.05% to about 10% by weight of the polyethylene oxide polymer backbone of at least one polar vinyl monomer grafted to the polyethylene oxide polymer backbone. One or more nanoscopic particulate processing aids may be uniformly dispersed in the graft polymer in an amount of from about 0.05% to about 10% by weight of the water-soluble thermoplastic polymer composite. The water-soluble thermoplastic polymer composite may have a viscosity in the range of about 100 to about 10,000 Pa-sec. The method may also include forming the water-soluble thermoplastic polymer composite into the 3D printable sacrificial support material.
